An early Edwardian-era halo ring pleases with a scale that is just right...neither too petite, nor too grand.

An oval, Australian opal cabochon possesses even coloration throughout the gemstone. Predominant tones include fiery oranges, parrot greens and yellows, in a backdrop with hints of purple. Weighing 1.75 carats, this opal is prong set for security, yet keeps the focus where it belongs.

With a frame of old mine cut diamonds, twelve in all, their total of 1.20 carats creates a border of glam. Alive with sparkle, their color range is H-K, and their clarity is SI1-3. That translates to showing nothing but white and bright shimmer, and with no internal inclusions that you will ever see with the naked eye.

The gem, powerfully packed with an interplay of scintillating hues is placed in a setting of 18k yellow gold. This antique ring is English and dates to about 1890. Note those swirling designs on the shoulds for an added touch of visual detail.
